Jack froze, a little taken aback at the sudden hug. Then again, he knew Fred well enough that it shouldn't have been a surprise.
He closed his eyes and gave her a gentle squeeze. The hug was more than welcome. Jack didn't have much in the way of friends in the City. After all, he didn't have time for a social life and it was a little awkward trying to meet new people when most knew who he was already.
He held on perhaps a little longer than he should have, but finally released the woman and smiled down at her as he tried to get back into 'stiff upper-lip' mode.
